Heat Treatment




General annealing after hammering: the heating temperature is 830-850 ℃, the furnace is cooled to below 550 ℃, the furnace is air cooled, and the hardness after annealing is 229hbw.

Isothermal annealing process after hammering: heating temperature 830-850 ℃, isothermal temperature 700-720 ℃, furnace cooling to 550 ℃, outgoing air cooling, hardness ≤ 229hbw, annealing metallographic structure is fine-grained pearlite + carbide.

After quenching and low-temperature tempering (960 ~ 980 degrees oil quenching, 200 ~ 300 degrees tempering), it contains about 8% ~ 10% carbide and 15% ~ 20% retained austenite. The tempering temperature is 150 ~ 170 ℃ and the hardness is 62 ~ 63hrc; Tempering is 190 ~ 210 degrees and hardness is 58 ~ 60HRC.

Features and Application


Cr6wv steel is widely used to manufacture molds with high mechanical strength, certain wear resistance and impact load, such as drill sleeve, cold stamping die and punch, trimming die, embossing die, thread rolling die, thread rolling plate, block gauge, etc.
